I have one of these running my Barton Mobile chip, think i paid $22 with free shipping. http://www.newegg.com/Product/Product.aspx?It … N82E16817103149
Hehe, look for my review. Still running but the fan's a little louder now.

Here's a great tool for figuring out wattage. http://extreme.outervision.com/psucalculatorlite.jsp

I am not sure, power is your problem. These old second hand cpus have sometimes been overclocked and overvolted by too much and for too long. Does the die show cracks in the corner?

I tried that calculator out a few days ago. It's very interesting. I vaguely remember in the dim and distant past buying the $2 "Pro" version, but I've no idea if or where my "purchase key" is. Anyway, using the "lite" version I put in a very basic configuration that had no HDD, no CD, and basic graphics. I tried a mobile barton 2200+. I get 96W result. Then I change the CPU for a t-bred 2400+, and get 122W. That's quite an increase. Then I set the capacitor aging to 30% Hehe, I reckon that's a conservative value on some of these KT133A "horror boards" I've been testing. The wattage result then jumps up to 158W!

It's difficult to say - generally speaking, it looks in rather poor condition. You know the die has a kind of light pink colour? Well, near the bottom right hand corner (but not right on the edge), it appears that a few tiny flakes/specks of this pink colour are missing - as if it's been scuffed/chipped away. Perhaps it is fractionally damaged in some way?

Sorry the photo's not very good. Here are the 2 CPUs. The bottom one in rather shocking condition is actually the one that "works". Hehe!

😳

Now I see why CPU manufacturers hide their cores beneath metal plates on newer processors... I'm surprised this works at all!

Normally the silvery thermal paste is not really conductive, but on both CPUs it is in places where it doesn't belong. I'm afraid there is no easy way to get rid of it, but soaking the whole CPU in something might be worth a try.

Remembers me of this website 😁

Bushwack, I've copied-and-pasted one of the photos from the above website. Do you remember I described one of my "smoked" CPUs as having "black goo" in the corner of the die. It was a bit like this photo, although not nearly as bad!

Have had some cpu's that were drenched in thermal compound like this.
I get the job done cleaning rhem with this (no rocket science)

It easily disolves different variants of thermal compound

So am I. But I just retested it, inside a Kinetiz KT133A based board. Surprisingly, it works fine - at "top speed": 2000mhz / 133fsb.

Ideally, I would like to buy a PSU from about 5 years ago, but which is "new old stock". An Antec or Enermax - one of the greats, with excellent 3.3 & 5 volt rails. I had a quick browse online at new and modern PSUs and found this one -

It has 40A on both 3 and 5 rails, but it's incredibly expensive.

That's like bringing a gun to a knife fight. The kind of gun you find on attack helicopters:

ohmegod....

clean those cpus before experimenting further
